Now, I don't want to pretend that your behavior isn't a factor in your life expectancy. It's actually a huge factor -- it's just another one you have surprisingly little control over. We all know that smoking will lower your life expectancy, as will drinking too much, being overweight, or writing for Cracked. We resolve to be better about these things, but despite our best efforts 67 percent of people with gym memberships can't even muster the get-up-and-go to use them once.

It turns out that knowing about the health risks of an activity has little to no effect on our ability to stop doing it. And it isn't us just being too weak to resist temptation when it's in front of us: We will actively pursue doing things that we know are bad for us with the tenacity of a drunken sophomore with his ex's phone number. When this country's government tried to prohibit people from drinking, in an era called The Stoppening, the country basically said, "Do we really need a government?" and gave all their money to hooch-pedaling gangsters. "People should stop drinking" is the only Constitutional amendment ever to be repealed completely. That happened because, given the choice between not drinking and empowering murderers who live by the law of the jungle, most people chose alcohol.

So, good luck changing your behavior to save your life. The odds are against you, and also, it very well may not matter.

Even if your genes aren't the problem per se, they may have caused you to be born into a group with greatly reduced life expectancy, like being a black male in the United States. Health tip: Do not be born into this group.

Or, you might just happen to be born into a time when a war is happening. More than 20 million citizens of the Soviet Union died during World War II because of a conflict between multiple abstract entities they had nothing to do with creating. If you were an able-bodied French man in 1913, you had a roughly 1 in 8 chance of being killed in World War I.

Survivors had an 8 in 8 chance of dying later, because death is the most ruthless warlord of all.

But that was decades ago. You might think current wars aren't so bad: We've got drones and stuff. In that case, you're only thinking about the sides that are flying drones, rather than the sides being droned or involved in civil wars with no drones. Without citing figures too depressing even for this article, suffice it to say that there are still plenty of places to be born today where you can be sucked up into a war that had nothing to do with you. Hell, you could be sitting in your house in Belgium when a Soviet jet runs out of fuel and crashes directly into your house, making you a casualty of the Cold War you didn't even realize you were about to participate in.

On the one hand, no boot camp assholes screaming at you because you can't do one push-up.
On the other hand, dead.

Or, you might just be born into a part of the world where you can be executed for who you are, like being in an ISIS-controlled territory and being gay. or being in the United States and not liking that new Star Wars movie. So don't be born in a place and time inhospitable to the kind of person you are.

Helpful hint: If you're poor, this may be basically all places and points in history.

If, somehow, rescue workers happen to be near the grain silo for some highly unlikely reason, you're still not out of the woods. Rescue workers must be specially trained in grain rescues because of the toxic fumes, further grain avalanches, and because pulling (rather than digging) a body out of corn requires 900 pounds of force -- enough to tear your arm off.

Since there won't always be rescue specialists around, be sure to avoid all the things that you aren't aware are mortal threats. Keep in mind that basically anything can be a mortal threat.

It may seem like everything is out to get you and you should just hole up in a bunker with a year's supply of food and the box set of Buffy The Vampire Slayer. Well, that's patently false. Everything isn't out to get you -- everything is out to get all of us. Some things are out to get all of us at once.

Experts have put their best guess at 19 percent for a civilization-ending catastrophe occurring in the next 85 years. With lifespans increasing, that probably means there's something like a 15 percent chance that you'll just be wiped out with most other humans by a global catastrophe, like weaponized nanobots or super-intelligent AI. I know I'd prefer to be wiped out by nanobots made by super-intelligent AI, so I could appreciate their elegant design as they tore me to death, molecule by molecule. But, of course, my preferences are obviously of no consequence in a world where Stella was canceled after one season.

Comedy Central
That AI would've been smart enough to keep them on the air. And then kill them, for they are flesh and they are weak.

Say you manage to avoid the metaphorical landmines of disease, war, and unforeseeable accidents, as well as the literal land filled with deadly, deadly mines. You still have a 15 percent chance of being taken out by an act of (proof-there-is-no-)God.

The discovery of the Hayflick phenomenon put a quick end to that bit of optimism. Every time one of your cells divides, the telomeres associated with that cell's DNA shorten until cell division is no longer possible. I don't really have a firm grasp on the specifics of the biology, but death certainly has a firm grasp on us, no matter what we do.

Our lumpy, clotting blood is on your hands, asshole.

I'm not saying there's nothing we can do to prolong our lives. Obviously, we can increase our chances of living longer by doing things like ignoring the trolls boycotting Ghostbusters. The point is that, even when we stack the odds in our favor as best we can, we still live in a world far more out of our control than we like to realize. Comets crash into planets, stars go nova, and films like The Force Awakens make a billion dollars in 12 days. Such is the randomness of the universe. Even when we do everything right, tons of people die for absolutely no discernible reason whatsoever.

All closed systems can only increase in entropy over time. The fact that we exist and have become complex enough to be freaked out by our existence is an improbable and temporary state of affairs. The universe is primarily filled with dark matter and dark energy that lay an invisible hand on the universe observable to us. That's a pretty dead giveaway that we live in a Lovecraftian nightmare world. I wonder if there's a juice cleanse for that.

Which Sci-Fi Trope Would You Bring To The Real World, And Why? Every summer, we're treated to the same buffet of three or four science fiction movies with the same basic conceits. There's man vs. aliens, man vs. robots, man vs. army of clones, and man vs. complicated time travel rules. With virtual reality and self-driving cars fast approaching, it's time to consider what type of sci-fi movie we want to be living in for the rest of our lives. Co-hosts Jack O'Brien and Adam Tod Brown are joined by Cracked's Tom Reimann and Josh Sargent and comedians David Huntsberger, Adam Newman, and Caitlin Gill to figure out which sci-fi trope would be the best to make a reality.
